Evaluate the function f(-2) - h(4) given the following functions: f(x) = 4x​ 2​+ 9 h(x) = 3x - 14

Answer:

-86

Step-by-step explanation:

simplify each equation as much as possible

f(x)= 4x(2+9) add

4x(11) multiply

f(x)=44x

substitute given numbers into each equation

44(-2)=-88                3(4)-14= 12-14=-2

combine equations

-88-(-2)= -86   add since you are subtracting a negative number

3. Solve for x.<br> 3r +11<br> 9x - 14<br> Plss
Studentka2010 [4]

Answer:

x=12

Step-by-step explanation:

use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)

2(3x +11) = 9x -14

6x +22 = 9x -14; distribute

6x -9x = -22-14; subtract 9x and 22 from both sides

-3x = -36; divide both sides by -3

x= 12

Suppose a punter kicks a football so that the upward component of its velocity is 80 feet per second. If the ball is 3 feet off
Alexxandr [17]
So hmm check the picture below

\bf \qquad \textit{initial velocity}\\\\ h = -16t^2+v_ot+h_o \qquad \text{in feet}\\&#10;\\&#10;v_o=\textit{initial velocity of the object}\\&#10;h_o=\textit{initial height of the object}\\&#10;h=\textit{height of the object at "t" seconds}\\\\&#10;-----------------------------\\\\&#10;h(t)=3+80t-16t^2\iff h(t)=-16t^2+80t+3

a)

well, clearly is 80 ft/s

b)

when t = 1? well 80(1)

c)

in the picture, x-axis is the time and y-axis is the height
so, it reaches its maximum at the vertex, after "x" seconds

\bf \begin{array}{lcccll}&#10;h(t)=&-16t^2&+80t&+3\\&#10;&\uparrow &\uparrow &\uparrow \\&#10;&a&b&c&#10;\end{array}\qquad &#10;\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

so it reached the vertex after \bf -\cfrac{{{ b}}}{2{{ a}}}\quad seconds

d)

the maximum height of the ball is \bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\quad feet
